Refocusing transportation planning for the 21st century : proceedings of two conferences, held in Washington, D.C., February 7-10, 1999 and in Irvine, California, April 25-28, 1999.

Two conferences were held in 1999 that followed the passage of the Transportation Equity Act for the 21st Century (TEA-21). The first conference, held in Washington, D.C., February 7-10, focused on the identification of key trends, issues, and general areas of research (not detailed statements). The results of Conference I, which produced standalone products, were used as input for Conference II, held in Irvine, California, April 25-28. Conference II had the specific objective of producing needs statements. Its mission was to review the results of the first conference by developing these statements. Conference II produced a number of detailed research statements that form the basis for the National Agenda for Transportation Planning Research. The proceedings of both conferences are presented in this report. (A)
